Clearance Rates Stuck Below 50%: What Tax Reforms Mean for Buyers

Capital city auction clearance rates slipped back below 50% in July as budget tax reforms and higher interest rates reshape buyer and investor demand.

Capital city auction clearance rates slipped back below 50 per cent on the weekend of 19 July, according to the latest data from Cotality, with Sydney showing the sharpest weakness of the major markets. The result extends a run of soft outcomes that has now stretched through most of winter — and it is landing squarely in the shadow of the biggest change to residential property tax settings in years.

MPA Australia reports that Sydney's clearance rate fell back under the 50 per cent mark last weekend, having only briefly pushed above that line the week before. Melbourne held up somewhat better. As Cotality research director Tim Lawless put it: "It does look like Sydney is wearing this weakness in clearance rates much more acutely than Melbourne, where we've been seeing clearance rates holding in that sort of mid-50 per cent range for the past three weeks now. It's still weak, but it looks like Sydney is showing a much weaker clearance trend."

The national clearance rate has spent the bulk of the past two months below 50 per cent, with occasional brief ticks above the line before retreating. MPA Australia also cautions that preliminary weekend reads are often revised down once final results are tallied later in the week, so individual readings should be treated with some care.

What the May 2026 budget reforms are doing to the market

The soft auction results are running alongside a structural shift in investor behaviour triggered by the federal government's May 2026 Budget. Under reforms announced on 12 May 2026 and confirmed in the Budget's official tax reform paper, negative gearing will be limited to new-build residential property from 1 July 2027. At the same time, the capital gains tax discount is being replaced with cost-base indexation and a minimum tax on gains.

Properties held before Budget night are grandfathered under the existing rules, but investors purchasing established dwellings after that date lose the ability to offset rental losses against wage income. That established dwelling segment is precisely what dominates the capital city auction calendar — making the timing and tenor of this clearance rate weakness more structural than cyclical.

The response from major lenders has been notable. Commonwealth Bank's modelling, as reported by MPA Australia, expects established dwelling prices to end up "noticeably softer" than they otherwise would have been, with the impact concentrated in apartments and lower-priced segments where investor participation is highest. Westpac's June Housing Pulse went further, warning of "a sustained withdrawal of investor demand from mid-2026."

Moody's Ratings, which published a separate analysis of the same reforms this week, said the combination of higher interest rates and the new tax settings would "slow property transaction volumes and constrain national house price growth." On the investor segment specifically, the agency said: "The short-term credit effects of the tax changes are likely to be negative. Lower credit demand from investors is unlikely to be offset by growth in demand from owner-occupiers."

But Moody's also flagged a longer-term upside: "these tax measures should improve housing affordability and increase supply as investor demand shifts to new builds, which are not affected by the tax changes."

What this means if you are buying or planning to buy

The picture for buyers right now is genuinely mixed, and which side of the ledger you are on depends largely on what stage you are at.

For first home buyers, the same dynamics suppressing clearance rates may actually create a more navigable purchase window. With fewer investors competing for the same pool of established dwellings at auction, buyers who come in owner-occupier-ready — with finance approved and a clear budget — may find the cleared field less intimidating than it has been in recent years. It is the kind of environment where getting your borrowing power confirmed in advance gives you a genuine edge at auction, because you can move decisively when others are hesitating.

For existing property owners and those looking to refinance, the broader context is one of cooling prices and softening credit demand nationally. That does not immediately change what you owe, but it does mean lenders are competing harder for a shrinking pool of borrowers. That competition tends to put pressure on rates, and reviewing your loan now — rather than waiting — means you are positioned to benefit if deals sharpen further.

For investors, the calculus has changed materially. Those with established dwelling portfolios bought before Budget night retain their grandfathered negative gearing entitlements, but should think carefully about their loan structures in a market where price growth looks constrained and delinquencies are flagged to rise. Looking at investor home loan options now, including whether a switch from interest-only to principal-and-interest makes sense, is worth a conversation with a broker.

The Equifax Consumer Market Pulse published this week reinforced the same theme from a different angle, showing overall mortgage demand down 14 per cent year on year in June — with no state or age group recording positive growth. Sydney and Melbourne are both feeling the weight of that double-hit from rate pressure and the structural investor pullback. The clearance rate data suggests that, for now, sellers and buyers alike are adjusting to a market that looks quite different from where it was 12 months ago.
